How to convert string to Array via javascript?

Question

I have following string in javascript variable

var days="1,2,3";

now I want this in following way as javascript variable with JSON format like

jdays=["1", "2", "3"];

Is there anyway to do so?

You want to remove 3? Try days.split(',');, or days.match(/\d+/g) — Tushar

@skiskd That is not JSON, it'a an array, check my previous comment to get the data in the array format — Tushar

This will work

var days = "1,2,3",
    jdays = days.split(',');
console.log(jdays); // ["1", "2", "3"]

String.prototype.split() is used to split a string into an array by removing every instance of the string passed to it as a parameter and pushing each fragment of the string to the array.

The array created by String.prototype.split() is the return value of the function.

FYI console.log(jdays); // [1, 2, 3] is wrong, jdays will be ["1", "2", "3"], note that the elements of array are strings not numbers

@Tushar Didn't see that... Thanks.

by using split function you can do this

 var daysArr = days.split(',')

If, when you say you "want this in following way as a javascript variable" you mean you want that JSON format string in a variable.. then..

jsonstring = 'jdays='+JSON.stringify(days.split(','));
